Abstract
A system, apparatus and method for inhibiting the ringer of a cellular telephone within a noise sensitive area includes a transmitter for generating a control signal within the area. A receiver within the cellular telephone generates a mute signal during reception of the control signal which inhibits operation of the telephone ringer circuit while the telephone is in the noise sensitive area. In an alternate embodiment, a transmitter of limited range is placed at each entrance to the noise sensitive area and the ringer circuit is inhibited upon momentarily receiving the control signal entering the area, and activated upon momentarily receiving the control signal exiting the area.
